HB 2612 changes evidence rules for medical bills in Oklahoma personal injury cases. It limits what can be shown in court to either the actual amount paid for treatment (if paid), Medicare reimbursement rates (if no payment was made), or the amount insurance would cover - whichever is lower. This applies to both past medical bills and future treatment costs, preventing courts from considering inflated "billed" amounts. The law takes effect November 1, 2025, affecting plaintiffs, medical providers, and defendants in personal injury lawsuits.
